Problem

Imagine that you are the database administrator for a military transportation system. You have a table named cargo in your database that contains information on the various cargo holds available on each outbound airplane. Each row in the table represents a single shipment and lists the contents of that shipment and the flight identification number. Only one shipment per hold is allowed. The flight identification number may be cross-referenced with other tables to determine the origin, destination, flight time, and similar data. The cargo table appears as follows:

Flight ID

Cargo Hold

Contents

Classification

A

Boots

Unclassified

1254

B

Guns

Unclassified

1254

C

Atomic bomb

Top Secret

D

Suppose that two roles are defined: Role 1 has full access rights to the cargo table. Role 2 has full access rights only to rows of the table in which the Classification field has the value Unclassified. Describe a scenario in which a user assigned to role 2 uses one or more queries to determine that there is a classified shipment on board the aircraft.
